I ride a Trek Stache 8, and am a huge fan. 29" tires are nice, but didn't blow my mind. Will probably go 27.5" when the time comes (years down the trail).
I will say I am a Craiglist proponent.
Got my first bike, Giant Rincon, barely used and a year old for $300 (new is $500), and just got this Stache for $800 lightly used and two years old, when new it would have been over $2K.
Both bikes have been great, and close to new condition.
Sorry I can't be of more use, but man, there are some sweet deals on CL...
